Nitrogen...

You could run the reactor with some nitrogen in it, at normal vacuum pressures, and the reaction itself would quench, but you could use the nitrogen plasma to nitride the boron. This would prevent your other bits and pieces from oxidizing. One must also conisder just how much boron powder/dust/etc. ...

.3m?

My original concept was a 1 cubic inch "reactor". I guess what you're saying is that this isn't a scalable technique? Also, keeping in mind that the required input power for the wiggle wouldn't be but a few watts - you only need to move the field a nanometer to get an electron to start turning - the...

point cusp/nongradient field...

I think that's what I'm addressing with the field wiggle. Isn't it pretty much the same problem with a coil? There's a line (albeit a single point, rather than a large part of the face of a permanent magnet) coaxial to the coil that permits a charged particle to escape along a free path straight out...

Re: Boron...

How would you go about purifying your own B11 from raw B10/11? Personally? I'd go to a boron dealer and buy it. Pure B11 and B10 are already commercially used and purified. How much for a dime bag? :-p Sorry, so so so so sorry. I just had this image of a shady guy in a trenchcoat standing on the co...

Boron...

Anyone think of borax? It should be nontrivial to coat the inside of the chamber with a material that would combine with boron to yield something along the lines of borax - nice and inert and non-toxic. I thought of using borax as a boron source, but the oxygen and sodium aren't all that reaction-fr...

Oh, he felt something

I doubt the frog felt anything. The effect happens because all materials are diamagnetic - the electrons all tend to line up against the imposed field. So that means the water and the frog in it were all evenly lifted. I wouldn't mind the experiment of being floated in a 20 T field, but that would ...

Heating + Containment?

I was originally going to post this elsewhere, but the post I was replying to turned out to be off-topic, so I'll toss it in here. I do understand that closed box reactors won't work because of cusp leakage and magnet impact. I think I have a way of making a workable closed box reactor, but that's n...

ZOMG!

I live not far from Jlab. Feel free to PM me with the name of the idiot deciding to use aluminum and I'll be happy to charge him a very large consulting fee the next time he wants to build something improperly. Ugh. Not to mention the difficulty with outgassing because aluminum (specifically the sur...

Why not go small?

And use large permanent magnets. Supermagnetman has a halbach array that puts 3T into about a cubic centimeter. This is the route I'm going for a demo of electron trapping in low pressure argon. I just want to visualize the electrons and plasma behavior, and not have to worry about neutrons. Will re...
